In order to meet the extreme operating requirements of semiconductor cleanrooms, amusement rides, automated material handling, and mining machinery, we customize high-performance polyurethane raw material systems including TDI, MDI, PPDI, NDI formulations.Each material has unique advantages in wear resistance, tear strength, hydrolysis resistance, high-temperature stability, dynamic fatigue life and anti-static performance. We select the optimal PU raw material formula according to different industry load, speed, temperature and environmental conditions, ensuring our wheels achieve longer service life and more stable running performance under complex working conditions.

Central to our production philosophy is the integration of Low-Free (LF) Monomer technology, a sophisticated process that reduces residual free isocyanate to less than 0.1%, effectively neutralizing the toxicity concerns traditionally associated with TDI while simultaneously creating a more uniform molecular network for superior dynamic load-bearing and extended service life.
